GEORGE SOHALGK, OF POTTSVILLE, PENNSYLVANIA.

TRIGGER VFOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 226,555, dated April 13, 188.0.

Application filed January 26, 18:50.

To all whom it 'may conccra:

Be it known that l, GEORGE SOI-IALGK, of Pott-sville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful lmprovements in Fire-Arms;

and I do hereby declarc that the following is a full, clear, and exact description of the invention, which will enable others skilled in the artl to which it appertains to make and use the same, reference being had to the accompanyingdrawin gs, and to the letters of reference marked thereou, which form a part of this specification.

This invention relates to an improvement in fire-arms; audit consists in the construction and arrangement of parts, as will be hercinafter more fully set forth. 4

In the annexed drawings, which fully illustrate my invention, Figure 1 is a longitudinal vertical section, showing` the guard-lever and breech-block in position for firing; Fig. 2, a similar section, showing the same parts in position for retracting and loading 5 Fig. 3, a side view of the trigger, ancl Fig. 4 a modification.

In the drawings, A indicates the stock; B, the barrcl 0, the breeeh-block 5 D, the guardlever; E, the hammer; F, the mainspring; a, dog 5 I), trigger; c, trigger-spring; d, roller in free end of spring; e, projcction on dog 5 f, dog-spring.

The stock A and barrel B are made in the usual or any well-known form, and the breechblock is provided with an ordinary I spring firing-pin, and is hinged at the rear end near the top to the stock, as shown. The under side of this block is provided with projections G' 0", for the purpose of operating it and locking it in position by the lever.

. The lever D is eurved to the rear to form a guard for the trigger, and its front or inner end is provided With branches or pron gs D' D".

The block G is provided at its rear end with a pivoted stud or arm, g, which sets the hammer when the block is thrown down for retraeting and loading, and is drawn out of the way of the hammer when the block is returned As shown, this pivoted stud is provided with a swinging guide, h, to keep it in position; but in practice this guide may be omitted and its place supplied by the gun-stock.

The lower end of the hammer is provided with the usual notch or notches for engaging With the dog, and the dog is provided with the spring f for causing it to engage with the notches, which spring may be of the form shown or of any other suitable form.. This dog a is provided with a pivoted trigger, b, as shown, and the trigger is provided with a spring, c, which is 'tastened to it at the lower end. The upper end of the spring is partly cut away and provided with the roller d. The dog a is also provided at its front 'with a small projeetion, e, which is traversed by the roller cl, which, as shown in Fig. 3, passes onto the upper face of the projection when the trigger is throwu forward, and onto the under face or away from it when the trigger is thrown back in the position shown in Fig. 1.

It is evident that the projeetion may be made on the spring and a depression in the dog, as shown at d' e in Fig. 4t, and the same result be accomplished. I

In operation, when the gun is to be fired the breech-block is held in position by its own- 'pivot and the end or prong D' of the lever D,

which is in line with the rear end of the cartridge and the lever-pivot, so that the block cannot be thrown down by the reaction of the firing. i The movements of the lever and block will be apparentfrom the description and drawin gs, and it will be seen that the movement of the block can be accomplished by the engagement of the prong D' with the projections O' O without the leVe1'-pro jection D";- but I have added that for the purpose of being doubly certain of the proper return of the block to its firing position.

The trigger Z) may be thrown forward into the position shown at Fig. 3 either before or afterthe hammer is coeked, or it may be used without being thrown forward at all. When thrown forward the roller d -passes onto the upper surface of the projection e on the dog, which movement strains the spring and holds the trigger.. By a very slight pull the spring- IOO By this arrangement the trigger is made to operateas a set or hair trigger, or it can be used as a straight pull, as may be desired. It can be inserted and usedV in any lock without Vtaking up any more room than an ordinary straight-pull trigger.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The dog a, having the projection e, in combination With the triggcr b, hin ged thereto, and

spring c, attached to the trigger, and having roller d working 011 projection e of the dog, substantially as specified.

In testirnony that I claim the foregoing as 15 my own I have hereto affixed my Signature inr presence of two witnesses.

'GEORGE SOHALOK.
